When to Call a Pool Leak Detection Company

Not sure when to call a pool leak detection company versus checking things yourself? The short rule: do the easy home checks first, but call a pro the moment you’ve confirmed a real loss and can’t pinpoint where it’s going. Guessing past that point is where homeowners waste money.

A few quick tests at home can rule a leak in or out. But once it’s clear water is escaping and the source isn’t obvious, a specialist with pressure and acoustic equipment will find it far faster — and cheaper — than trial and error.

Signs It’s Time to Call a Pro

Any one of these is a good reason to stop guessing and book a detection:

• You’re refilling often. Adding water every few days, or losing more than about a quarter-inch a day beyond normal evaporation.
• Air bubbles blow from the return jets. That points to a suction-side leak drawing air into the plumbing.
• Wet spots, soggy soil, or a sinking deck. Signs water is escaping underground and moving through the yard.
• The water stops at a specific point. Dropping to the skimmer, a return, or the light and then holding suggests a leak right at that spot.
• Your equipment pad stays wet. Drips at the pump, filter, or valves that you can’t trace or stop.
• You’ve done the home checks and they’re inconclusive. You confirmed a loss but can’t find the source — exactly what pros are for.

If several of these sound familiar, our rundown of the common signs your pool has a leak goes deeper on each one.

When You Can Probably Check It Yourself First

Not every drop in water level needs a service call. You can reasonably start on your own when:

• The loss is small and steady. A slow, unchanging drop in Arizona’s heat is often just evaporation.
• You haven’t run a bucket test yet. It’s the simplest way to separate a leak from evaporation before spending anything.
• Nothing else looks wrong. No wet spots, no bubbles, no cracks — just a bit of summer evaporation.

Those home checks are worth doing first — our guide to DIY pool leak testing walks through the bucket test and a few others, and telling a leak from evaporation is the single most useful check before you call anyone.

Why Calling Sooner Usually Saves Money

Waiting rarely helps a real leak. The longer water escapes, the more it can erode soil, undermine the deck, or worsen a crack — turning a small repair into a big one. A prompt detection also means you’re only paying to fix a confirmed problem, which is why it’s almost always worth having detection done rather than living with a mystery loss.

What to Have Ready When You Call

A good company will ask a few questions up front. Having these answers ready makes the visit faster and more accurate:

• How much water you’re losing, and how fast.
• Whether the loss happens with the pump running, off, or both.
• Where the water level finally stops dropping.
• Any recent repairs, remodeling, or landscaping.
• Whether you’ve noticed bubbles, wet spots, or cracks.

When you’re ready, a professional pool leak detection service takes it from there — confirming the leak and pinpointing the exact source in a single visit.

Frequently Asked Questions

Should I try to find the leak myself before calling?

A couple of simple checks are worth doing — a bucket test to rule out evaporation, and a look for obvious wet spots or bubbles. But if those don’t pinpoint it, calling a pro is faster and cheaper than tearing into your plumbing on a guess.

Is a fast water loss an emergency?

It’s not usually a middle-of-the-night emergency, but a fast loss (an inch or more a day) is worth a prompt call. Rapid loss can point to a broken line that’s also wasting a lot of water and eroding soil.

Will a company come out just to check if I even have a leak?

Yes. Confirming whether a leak exists is part of a detection. If it turns out to be evaporation, a reputable company will tell you that instead of inventing a repair.

How soon can most companies come out?

Often within a few days, sometimes sooner. Because detection is a single-visit job, you’ll usually have your answer the same day they arrive.

The Bottom Line

Do the easy home checks first — but once a real loss is confirmed and the source isn’t obvious, calling a pro is the fastest, cheapest way to an answer.
